Key Products

Improved traffic light management can help administrator to control vehicle flow and mitigate congestion, thus reducing transit time and associated carbon emissions. In addition to the basic function of a traffic light - Display Unit, with green, red and orange LEDs, it may incorporate a Detector Unit, with sensors for detecting vehicles or pedestrian and a Controller Unit - smart traffic light can be equipped with cameras to detect infringements to traffic code and registration plate recognition as well as connectivity to enable centralized control.
